This is a hilarious thread. People think that just because they have the HP, that their driveline and tires are capable of safely going above the factory governed speed. People stating that they've gone north of 120 in a lifted full size pickup on presumably public road shouldn't be allowed to drive.

  If the tires are up to it modern vehicles have no problems operating well into the triple digits. It's just a wear and tear issue. Things don't spontaneously explode if you go too fast.

    Most modern cars, sure, but I wouldn't feel the same about a lifted truck with 36" mud terrain tires as mentioned in that thread. In a stock solid axle pickup, you somewhat frequently encounter what is referred to as a "death wobble" where the whole vehicle shakes, even at moderate speeds. Suspensions in full size trucks are commonly using 1950's era tech, not modern double wishbone or multilink setups that many cars have. This ignores that when you get into triple digit speeds, even small things like wheel balancing can make a huge difference for safety and performance (ignoring speed rating of tires). Most of the people commenting in that thread seemed to have lifted trucks (ignoring body vs suspension lifts or that they took cheap route to do so, e.g. grade 5 vs 8 hardware), so they are already changing things like center of gravity, aero and handling.

  Well it should be. - Tyres have well-defined speed ratings - It's not illegal to drive >120mph. It's only illegal to do it on public roads.

Appears to be about a system in normal RAMs, not specific to this Finland thing. I’d be curious if it’s the same speed limiter with a variable changed, or a different easier-to-remove system.

  Most "handheld tuners" can adjust the speed limiter without issue. Newer Dodge products need a PCM reflash in order to use the handheld tuner. Some tuning shops can do this on site, but I think a Finnish person would need to ship their PCM to the USA for a reflash, or buy a second flashed unit. Being a Hennessey product, this probably comes with a flashed PCM and the handheld tuner for it. I wouldn't be surprised if the manual came with a section stating something like, "this setting right here will adjust the speed limiter on your vehicle. It would be VERY ILLEGAL to use this feature to CHANGE THE TOP SPEED LIMITER to beyond 55MPH. Please don't use this feature if you're in the EU."
